Catch Tank

Featured Replies

Will be ordering a catch tank this month, can anyone show me pictures of your catch tank install and or pictures of the mounting.

Can anyone recommend a catch tank to purchase? I want something in black to make it look OEM as possible.

In all seriousness I would go for something off ebay, if you get one that is bolted together you can put your own baffling inside - people seem to think wire wool works well. Personally I'm going to go for a low low density foam, I have a feeling the wire wool could go a little rusty and I don't like the idea of it breaking up.

Will save you a fair bit of money doing a tiny bit of DIY :thumbup:

It's on my to do list, if I get it done soon I'll put some pictures up.

Yeah that looks ok, nice to get the brackets etc.

But...there isn't a filter and the intake/out-take ports are next to each other so all the space below is almost wasted.

You want the oil/air mixture to re condense so you don't burn the stuff.

Here is the sort of thing I mean:

So the standard catch can is on the left and the pimped one on the right...

Hopefully that makes sense?

Yeah that makes sense, thinking about it I dont want a filter/breather on the top so that D1 is out of the question I will be circulating the air back into intake once its passed in and out of the catch can, is there any catch cans on the market with a pipe that drops the oil down the bottom?

I was wondering if a plumbing supplier would have a 15mm hose fitting which is double ended meaning there will be the same inside as you get on the outside, then its a case of putting a bit of pipe on the inside to reach near the bottom.

Baffling with wire wool wont be a problem will it as the oil will keep the wire from rusting etc?

Also interested in this, as been looking at what to get and seen people putting wire wool in them?

I think it depends on how much oil you get through. Also if the oil goes to the bottom and the lighter stuff goes up and out i.e. air with water in (possibly) then parts of it could well rust. I don't think it's worth chancing it...the possibly of getting s***y bits of wire in your engine (if you plumb the catch can back to the air inlet) doesn't sound like a good idea to me!

I'm not too sure what you mean about the 15mm same on the inside and out???

I wouldn't put the pipe too near the bottom as this affects how much oil you can hold. Shouldn't be much but something worth considering.

I am going to get a can and then see what my options are with regards to pipe and baffles.

Anyone got any pictures of a can mounted? I hear the best place is next to the intake pipe for the air box?

You want to put brillo pads in further catch oil vapour - this makes the CC more effective.

Also it will take the shortest route out, usually back upto the top so if your happy vent to atmosphere but put a filter on half way down, but the pipe that goes to bottom is a good idea.

I use a Draft 42 catch can. Got it from Awesome GTI. Same size inlet/outlets too, 19mm? They come in black or stainless, and emptied from the bottom. Great piece of kit.

You REALLY DO NOT want to be using ordinary wire wool. The inside of a catch can gets oily but also attracts massive condensation due to heat cycling. One reason you pour catch can contents away rather than pour them back into the engine. The guy linked in the Freedom gallery didn't use wire wool or ordinary scourers in his catch can. It looks likely he used something like this - http://www.caterfor.co.uk/cleaning/cleaning-cloths/scourers-sponges/stainless-steel-scrubber-scourer-cf-j867?iv=1

Another thing to bear in mind. Whilst any filter medium will help, the best thing you can do is to fit a very large catch can. The air/oil mixture slows when it reaches a catch can and oil/water droplets fall out of suspension. The bigger the can, the better the effect.

From one of my favourite sites...

"The filter medium used inside the separator comprises stainless steel kitchen scourers. These can be quite expensive, but we sourced 'home brand' examples from a local supermarket for just 70 cents a packet. We bought five packets. Make sure that the scourer material is fairly hefty, so it's not gonna fall apart due to vibration.

The main body of the separator was then packed with scourers...."

So best thing to use for baffle is stainless steel scourers?

I was in the middle of production of a full catch can kit inc brackets, but sickness through Jan & Feb has basically stopped me doing any R & D on the kit!

Its a left side bracket with a rectangular catch can, an inlet & outlet & a vent filter along with fitments from the breather and back to the inlet.

Yeah I contacted you about that, how long until you finish the kit and start selling it?

Yup your right, not brillo pads. I've had steel scourers in my CC for 2 years now and no problems.

You don't need to use a massive catchcan, simply take out the dipstick and pipes from the ports if there is a difference in air flow then you know your catch can is too small or too big, however as i say venting with a filter is best.

I had experimented with a couple of idea's, basically a catch tank with a small breather filter inside;

2011-05-30170852.jpg

The first one proved to be too big and heavy so was scrapped.

The second attempt is a lot smaller and lighter without a drainage plug and with the top flange on the inside;

I'm going to have a go at finishing it this weekend and mounting it to the airbox as the main reason I gave up was trying to find a suitable mounting place.

Finger crossed the first ones should be ready in maybe 2 weeks or so. Im still signed off sick!

Hey, Ive just stumbeld across this article on the net -> DIY catch tank

Very cheap to make, looks good (could style it up with some vrs badges or whatever) and the best thing is you can make it to the size you want so you could fit it i.e. behind the front bumper. Couple of pipe clips to hold it and job done. Ive decided to go this route as my ol' man is a plumber, it makes sense :thumbup:

I rather like that idea... :)

with a catch can am I best having a three port to allow for a breather? IE in, out and a small filter.

Get your money out and buy a allard one, you tight lot... LOL
